Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 263 words
An enclosure arrangement for use in connection with a boot whereby a booted foot will be warmed selectively by a warming device, the boot having a longitudinally extending sole and an upper extending altitudinally from a welt area at the intersection of the sole and the upper, the sole including a toe end, a heel end and a shank between the toe end and heel end, and the upper including a toe adjacent the toe end, a counter adjacent the heel end, a sheath extending altitudinally between the toe and the counter and an apertured instep portion located between the toe and the sheath, the enclosure arrangement comprising: an enclosure member having a wall, the wall including first edge areas for extending generally longitudinally along the welt area between the toe end of the sole and the shank, and second edge areas for extending generally altitudinally along the upper between the welt area, adjacent the shank, and a location on the sheath spaced altitudinally from the apertured instep portion a distance sufficient to establish a chamber overlying the apertured instep portion between the toe of the upper and the sheath; means for joining the first and second edge areas with the boot so as to secure the enclosure member to the boot and establish a seal along said edges for sealing the chamber; an access opening in the wall of the enclosure member and juxtaposed with the chamber to enable selective access to the chamber for placement therein of the warming device; and closure means for selectively opening and closing the access opening.
Claim 2
Dependent Claim 263 words
An enclosure arrangement for use in connection with a boot whereby a booted foot will be warmed selectively by a warming device, the boot having a longitudinally extending sole and an upper extending altitudinally from a welt area at the intersection of the sole and the upper, the sole including a toe end, a heel end and a shank between the toe end and heel end, and the upper including a toe adjacent the toe end, a counter adjacent the heel end, a sheath extending altitudinally between the toe and the counter and an apertured instep portion located between the toe and the sheath, the enclosure arrangement comprising: an enclosure member having a wall, the wall including first edge areas for extending generally longitudinally along the welt area between the toe end of the sole and the shank, and second edge areas for extending generally altitudinally along the upper between the welt area, adjacent the shank, and a location on the sheath spaced altitudinally from the apertured instep portion a distance sufficient to establish a chamber overlying the apertured instep portion between the toe of the upper and the sheath; means for joining the first and second edge areas with the boot so as to secure the enclosure member to the boot and establish a seal along said edges for sealing the chamber; an access opening in the wall of the enclosure member and juxtaposed with the chamber to enable selective access to the chamber for placement therein of the warming device; and closure means for selectively opening and closing the access opening.
